Question

The minute hand of a circular clock is 14 cm. How far does the tip of the minute hand move in 1 hour?

Answer 1

In one 1 hour, the tip will complete one rotation.

One rotation means the circumference of the whole circle.

So radius = length of minute hand.

Radius = 14 cm

so, Distance the tip of the minute hand move in 1 hour $=2\pi r$

=$2\times \frac{22}{7}\times 14$

$=88cm$
